Synergetic ER-targeting Liposome Nanocarriers with Anti-phagocytic property for Enhanced Tumors Theranostics

Multifunctional nanocarriers have been widely applied due to their enhanced effect on tumor therapeutics. Nevertheless, owing to the natural immune clearance mechanisms in living bodies, nanocarriers tend to be eliminated during blood circulation, thereby impeding their effective arrival at the tumor sites. In a recently published paper, the authors constructed a synergetic targeted liposome nanocarrier system named SELS functionalized with both a tumor identification ligand (anti-ER (Estrogen Receptor) antibody) and an immune targeting ligand (Self-Peptide (SP)). DSPE-PEG-Mal (Nanosoft Polymers) was used to conjugate targeting ligand. The anti-ER antibody could recognize and bind ER-positive breast cancer tissues in a specific way. SP could activate the CD47-SIRPα immune response, which reduced phagocytosis of the nanoparticles by macrophages. Both the enhanced targeting ability and anti-phagocytosis behavior could improve the tumor uptake of the nanocarriers and prevent their immune clearance in living systems. Therefore, drug-loaded SELS enabled improved tumor imaging and therapeutic performance in living systems.  Journal of Materials Chemistry B, 48(7 ) 1056-1063.  2019.

NSP’s PLL-g-PEG was used in research for Long-Term Cell Fate Tracking of Individual Renal Cells Using Serial Intravital Microscopy.

Intravital multiphoton microscopy of the kidney is a powerful technique to study alterations in tissue morphology and function simultaneously in the living animal and represents a dynamic and developing research tool in the field. Recent technological advances include serial intravital multiphoton microscopy of the same kidney regions over several weeks and combined with ex vivo histology for cellular biomarker expression of the same cells, which had been subject to serial imaging before. Thus, serial intravital multiphoton microscopy followed by ex vivo histology provides unique tools to perform long-term cell fate tracing of the same renal cells during physiological and pathophysiological conditions, thereby allowing the detection of structural changes of the same renal cells over time. Examples include renal cell migration and proliferation while linking these events to local functional alterations and eventually to the expression of distinct cellular biomarkers. Recently a protocol for long-term cell fate tracking of individual renal cells was published using serial intravital microscopy. The authors provided a detailed step-by-step protocol to facilitate serial intravital multiphoton microscopy for long-term in vivo tracking of renal cells and subsequent ex vivo histology for immunohistological staining of the same cells in the fixed tissue.  Schiessl I.M., Fremter K., Burford J.L., Castrop H., Peti-Peterdi J.
